data T i a Source

A Physics.Quantity.Value.T combines a numeric value with a physical unit. Constructors Cons (T i) a Instances (Ord i, C a v) => C a (T i v) (Ord i, C a v) => C a (T i v) C a v => C a (T i v) Monad (T i) Functor (T i) Ord i => C (T i) (Eq i, Eq a) => Eq (T i a) (Ord i, Ord a) => Ord (T i a) (Ord i, Enum i, Show a) => Show (T i a) (Ord i, C a) => C (T i a) (Ord i, C a) => C (T i a) C v => C (T a v) (Ord i, C a) => C (T i a) (Ord i, C a) => C (T i a) (Ord i, C a) => C (T i a) (Ord i, C a) => C (T i a)

quantity :: (Ord i, Enum i, C a) => [Int] -> a -> T i a Source

Construct a physical value from a numeric value and the full vector representation of a unit.

fromScalarSingle :: a -> T i a Source

isScalar :: T i a -> Bool Source

Test for the neutral Unit.T. Also a zero has a unit!

lift :: (a -> b) -> T i a -> T i b Source

apply a function to the numeric value while preserving the unit

lift2 :: Eq i => String -> (a -> b -> c) -> T i a -> T i b -> T i c Source

lift2Maybe :: Eq i => (a -> b -> c) -> T i a -> T i b -> Maybe (T i c) Source

lift2Gen :: Eq i => String -> (a -> b -> c) -> T i a -> T i b -> c Source

errorUnitMismatch :: String -> a Source

addMaybe :: (Eq i, C a) => T i a -> T i a -> Maybe (T i a) Source

Add two values if the units match, otherwise return Nothing

subMaybe :: (Eq i, C a) => T i a -> T i a -> Maybe (T i a) Source

Subtract two values if the units match, otherwise return Nothing

scale :: (Ord i, C a) => a -> T i a -> T i a Source

ratPow :: C a => T Int -> T i a -> T i a Source

ratPowMaybe :: C a => T Int -> T i a -> Maybe (T i a) Source

fromRatio :: (C b, C a) => T a -> b Source
